Phil Spector used to take calls from Tina Turner and John Lennon, but now the only person who wants to work with him is mass murderer Charles Manson.
Manson is anxious to make music with the 69-year-old producer, who is serving life in prison for the shooting of actress Lana Clarkson.
Spector's wife Rachelle told a U.S. newspaper: 'A guard brought Philip a note from Manson.
'He said he considers Philip the greatest producer who ever lived. It was creepy. Philip didn't respond.'
Manson, 74, is being held at Corcoran State Prison in Los Angeles, where he is serving a life sentence for conspiring to murder seven people, including movie star Sharon Tate, in 1969.
'I think Manson wants to glean some musical advice from Phil, who was a Sixties music god with his "Wall of Sound",' publicist Hal Lifson said.
'But Phil's like, "I used to pick up the phone and it was John Lennon or Celine Dion or Tina Turner and now Charles Manson is trying to get a hold of me!".'
Manson is being held in a separate wing to the producer of hits Be My Baby and Unchained Melody.
The cult leader was initially sentenced to death in 1969 for the deaths of movie star Sharon Tate, coffee heiress Abigail Folger and three others stabbed and shot to death at Tate's LA home.
